V'ITNSSSES Lau/ .ff @www application :le December e, 199'?. Seal No. 0MB-@ To all whom i 'may consom? Be it known time "i, HORACE E GRANT, of Pittsburgh, Allegheny eoiznty, Pennsylvanie., lieve inve ted e new end useful Liquid-Supply System, of which "the following; is a full., clear, and emc descripioii; eei-eiiee heilig had to elle eeeompeiiying drewiegs, forming part of this speciiicaioii, in Which- 4 Figure l is e sectional side elevation showing one {om} of my improved gesolene supply system; Figs Q and a3 are detail views of the valve which l pieei' to employ; and Fig. 4f is e View similai lo l showing e modified form.

My invention ielees to that Claes of ,graso-- iene or liquid supply tanks wlieein I-tlie liquid is forced out iimlei air pressure io the point of use.

The object of the invention is to obviate the diieulty of forcing out lie gesolene after che tank lies been emptied of the major quantity therein.

Hereofore eter the gesolene tank Wes nearly emptied, or che gasolene Wes ieduced to e small amount berein, it was neeeeseiy to mise the air pressure to a high amountin order to force out the liquid, and 'this oonsumefl Considerable time and leboi.

My invenion is designe to overcome. this dioulty, and it consists in providing a supplemental tank into which the liquid is fed from the main tank by gravity, the aii' pressure entering this supplemental milk. The supplemental *Lenk being small compare izo the main tank, e smell amount of uii Will force out the liquid wt any Agime, and labor is greatly reduced.

Many changes may be made in the form and arrangement of the tanks, the eil' supply system, &c., withoutydeparting :from my invention.

In a storage supply system for inammable liquids, a main tank, a supplemental tank, a gravity feed connection between the tWo tanks, a delivery pipe having a passage extending upwardly throu h the said feed connection, and e check va ve fon said oonnectlon interpesedin said passage and enn Ai-,eaaseie posed 'te J the oniowing iiquioi therein, L; Wherey the pressure of the outfiowing iiquid tends to hold the Valve in position to dose-the communication between the two tanks, together withmeans for creating a gxntessure in the supplemental tank; sub- 2@ sftantiaiiy as described.
